Warning-free clang-format plugin install for VS 15.0
With the new release of VS, it's required that all plugins migrate to
the new VSIX manifest format. The new format is backwards compatible
with all versions newer that Visual Studio 2012, so this migration
effectively drops support for older versions of the IDE.
It's also required that these new extensions are built with Visual
Studio 2017, so unfortunately it was necessary to migrate the project
and solution. Also removed COM references to EnvDTE and
Microsoft.VisualStudio.TextManager.Interop from the csproj, as they seem
to both be unnecessary and would trigger build warnings because of
changes to GAC.

Summary:
The linker needs to be able to determine whether a symbol is text or data to
handle the case of a common being overridden by a strong definition in an
archive. If the archive contains a text member of the same name as the common,
that function is discarded. However, if the archive contains a data member of
the same name, that strong definition overrides the common. This is a behavior
of ld.bfd, which the Qualcomm linker also supports in LTO.
Here's a test case to illustrate:
####
cat > 1.c << \!
int blah;
!
cat > 2.c << \!
int blah() {
return 0;
}
!
cat > 3.c << \!
int blah = 20;

clang -c 2.c
clang -c 3.c

Summary:
APInt is currently implemented with an unsigned BitWidth field first and then a uint_64/pointer union. Due to the 64-bit size of the union there is a hole after the bitwidth.
Putting the union first allows the class to be packed. Making it 12 bytes instead of 16 bytes. An APSInt goes from 20 bytes to 16 bytes.
This shows a 4k reduction on the size of the opt binary on my local x86-64 build. So this enables some other improvement to the code as well.

Support: Add a VCSRevision.h header file.
This is a magic header file supported by the build system that provides a
single definition, LLVM_REVISION, containing an LLVM revision identifier,
if available. This functionality previously lived in the LTO library, but
I am moving it out to lib/Support because I want to also start using it in
lib/Object to create the IR symbol table.
This change also fixes a bug where LLVM_REVISION was never actually being
used in lib/LTO because the macro HAS_LLVM_REVISION was never defined (it
was misspelled as HAVE_SVN_VERSION_INC in lib/LTO/CMakeLists.txt, and was
only being defined in a non-existent file Version.cpp).
I also changed the code to use "git rev-parse --git-dir" to locate the .git
directory, instead of looking for it in the LLVM source root directory,
which makes this compatible with monorepos as well as git worktrees.

Summary:
__compressed_pair takes and passes it's constructor arguments by value. This causes arguments to be moved 3 times instead of once. This patch addresses that issue and fixes `constexpr` on the constructors.
I would rather have this fix than D27564, and I'm fairly confident it's not ABI breaking but I'm not 100% sure.
I prefer this solution because it removes a lot of code and makes the implementation *much* smaller.

ArgList: cache index ranges containing arguments with each ID
Improve performance of argument list parsing with large numbers of IDs and
large numbers of arguments, by tracking a conservative range of indexes within
the argument list that might contain an argument with each ID. In the worst
case (when the first and last argument with a given ID are at the opposite ends
of the argument list), this still results in a linear-time walk of the list,
but it helps substantially in the common case where each ID occurs only once,
or a few times close together in the list.
This gives a ~10x speedup to clang's `test/Driver/response-file.c`, which
constructs a very large set of command line arguments and feeds them to the
clang driver.

[llvm-pdbdump] Minor prepatory refactor of Class Def Dumper.
In a followup patch I intend to introduce an additional dumping
mode which dumps a graphical representation of a class's layout.
In preparation for this, the text-based layout printer needs to
be split out from the graphical layout printer, and both need
to be able to use the same code for printing the intro and outro
of a class's definition (e.g. base class list, etc).
This patch does so, and in the process introduces a skeleton
definition for the graphical printer, while currently making
the graphical printer just print nothing.

[llvm-pdbdump] More advanced class definition dumping.
Previously the dumping of class definitions was very primitive,
and it made it hard to do more than the most trivial of output
formats when dumping. As such, we would only dump one line for
each field, and then dump non-layout items like nested types
and enums.
With this patch, we do a complete analysis of the object
hierarchy including aggregate types, bases, virtual bases,
vftable analysis, etc. The only immediately visible effects
of this are that a) we can now dump a line for the vfptr where
before we would treat that as padding, and b) we now don't
treat virtual bases that come at the end of a class as padding
since we have a more detailed analysis of the class's storage
usage.
In subsequent patches, we should be able to use this analysis
to display a complete graphical view of a class's layout including
recursing arbitrarily deep into an object's base class / aggregate
member hierarchy.
